New WHO guidelines suggest usage of negative pressure wound system to reduce surgical site infections

The World Health Organization (WHO) has released new global guidelines recommending usage of negative pressure wound system to reduce costs associated with surgical site infections (SSI) related patient complications.

The new guidelines suggested the usage of prophylactic negative pressure wound therapy (pNPWT, or closed incision negative pressure therapy [ciNPT]) on primarily closed surgical incisions in high-risk wounds to prevent SSIs.

The guidelines were made in response to the impact of SSIs on global healthcare systems based on financial terms as well as patient outcome.

"The new WHO guidelines build upon a significant body of evidence that illustrates the impact negative pressure therapy can have in reducing the incidence of surgical site infections."

WHO developed the guidelines based on the findings of a systematic review and meta-analysis of 21 studies including both randomised controlled trials and observational studies using Acelity negative pressure therapy products such as the PREVENA Incision Management System.

Results of the study suggested that usage of pNPWT reduced the risk of SSIs compared to conventional dry gauze dressings.

Acelity’s PREVENA Incision Management System covers and shields the surgical incision from external contamination, while it exerts negative pressure for the removal of fluid and infectious material from the incision.

The lightweight and portable system features a replaceable canister, audible and visual alarms and an optional connector to allow the system to be used with certain VAC Negative Pressure Wound Therapy Units.

Acelity chief medical officer Ron Silverman said: “The new WHO guidelines build upon a significant body of evidence that illustrates the impact negative pressure therapy can have in reducing the incidence of surgical site infections.

“We developed PREVENA Therapy as the first disposable powered negative pressure system designed specifically for the management of closed surgical incisions six years ago, building off our demonstrated expertise in this space."
